These are great! I'll have to check what you two guys have said. I have a device which streams hd wireless from my laptop to my projector (although I use it mostly on my LCD in the bedroom). I have used it only for surfing the web and you can see it here:
CompUSA.com | USB-AV2010 | Cables Unlimited USB-AV2010 Wireless Adapter. I don't have hdmi out of my laptop so I hook this transmitter to a usb port which sends the signal to the receiver connected via hdmi to the tv. The picture is perfect, but not for movies which still stutter and sometimes even stop for buffering.
Then I bought a cheapo of the same thing that is hard wired from the usb port to a connector that runs an hdmi cable to my A/V receiver, which in turn is a pass through to the projector. This is the device I really wanted to stream my movies with because it is 1080p capable:
Mygica USB to 1080P Graphic Adapter for Video and Audio, US195A Graphic Adapter with Audio. It works good too for everything but movies which also stutter. I even hooked it up to my Dell PC Optiplex that I got just the other day but that did not help either. When I play the movies on the computer itself, I don't get nearly the stuttering on HBO that I get on MaxGo. I can not click on the HD in MaxGo anyway or it will just stop, so I'm stuck with SD. The 3mb speed increase has not helped and I think it is part of what you are all saying. These devices I have show "connect to projector" and I have tired every option - mirror, screen off, extend, split, and anything else they have available. Nothing helps. Maybe it is my graphics cards. The laptop and PC are not top of the line for sure but they are not old so I don't know. I will keep experimenting and see what happens.
